Patent CA-2362020-A1 (CA)
Inventor: TIEMANN PETER
IPC: F01D5/18
Filed: 2001-11-14
Abstract: The present invention relates to a gas turbine blade (1) with a closed steam cooling system. A partition (37) that is, in particular, of sheet metal divides a first partial cavity (23) in an axial direction so that steam can flow from the first secondary chamber (31) into a leading edge cavity (21) so as to cool this by impingement, and from this into a second secondary chamber (33). This entails the advantage of a configuration for a closed steam cooling system that is cost effective and particularly simple from the standpoint of production technique, and at the same time ensures a leading edge (11) that is of an aerodynamically efficient shape.

Title: Radial self-propagation pattern generation for disk file servowriting
Inventor: WEBB BUCKNELL C
IPC: G11B5/55
Filed: 1995-11-24
Abstract: During a write revolution of a storage medium, a transition is written on the storage medium while servoing on another transition previously recorded on the storage medium. During that write revolution, a position error signal corresponding to the position error of the transducer relative to the previously recorded transition is determined. That position error signal is then stored, during the write revolution, to be used in computing a reference track value associated with the transition being written to correct for the position error. Additionally, a product servo-pattern is written, which includes an embodying of the position error therein.

Patent CA-2368214-A1 (CA)
Title: Diminution du potentiel allergenique d'allergenes portes par l'air ou agissant par contact a l'aide de thioredoxine
Inventor: WONG JOSHUA H
IPC: A23L7/109
Filed: 2000-01-25
Abstract: Cette invention concerne une thioredoxine, une petite protéine de dithiol, qui réduit spécifiquement les protéines allergéniques, notamment celles présentes dans le pollen et dans des sources animales ou végétales. Toutes les protéines ciblées contiennent des liaisons disulfure (S-S) qui sont réduites au niveau de sulfhydryle (SH) par la thioredoxine. Ces protéines possèdent une activité allergénique et sont moins digestibles à l'état oxydé (S-S). Lorsqu'elles se trouvent à l'état réduit (SH), elles perdent leurs capacités allergéniques et/ou deviennent plus digestibles. La thioredoxine permet d'effectuer cette réduction lorsqu'elle est activée (réduite) soit par NADPH à l'aide d'une réductase de NADP-thioredoxine (états physiologiques), soit par un agent de réduction chimique à base d'acide lipoïque. Les tests cutanés menés sur des chiens sensibilisés ont montré que le traitement des pollens à l'aide d'une thioredoxine réduite avant l'injection, permettait d'éliminer ou de diminuer les capacités allergéniques du pollen. Des études ont permis de démontrer une digestion accrue des protéines de pollen par une pepsine suite à une réduction par thioredoxine. Les protéines de pollen réduites par thioredoxine consistent en des agents immuno-thérapeutiques sûrs et efficaces qui permettent de diminuer ou d'éliminer la réaction allergique d'un animal qui aurait normalement lieu lors d'une exposition à une protéine de pollen non réduite.

Patent CA-2372987-A1 (CA)
Inventor: WISEMAN THOMAS R
IPC: F23G7/08
Filed: 2002-02-25
Abstract: Liquids recovered from a gas well processed in a ground flare for avoiding the expense of offsite disposal. Well gases are burned in first burners to form a primary combustion zone. Liquids for disposal are introduced and atomized through second burners or nozzles into the primary combustion zone.  Preferably, a wellhead separator further separates liquids from gas recovered from the well. Liquids are stored in a tank and delivered to the second burners as the heat capacity in the flare permits. Supplementary commercial pilot gas can provide sufficient heat capacity if the well gas is temporarily insufficient. The liquid is incinerated and its combustion or vaporized products are discharged with the burned gas.

Title: Pilot nozzle for a gas turbine combustor and supply path converter
Inventor: AKAGI KOUICHI
IPC: F23R3/34
Filed: 2002-03-22
Abstract: This pilot nozzle has a fuel oil supply pipe disposed at the center of a heat-shielding air layer that is provided along an axial core, and a plurality of atomizing-fluid supply paths are disposed in the circumferential direction of a cylinder unit that surrounds the outside of the heat-shielding air layer. The atomizing-fluid supply paths and the fuel gas supply paths are disposed alternately and uniformly. Based on this structure, it is possible to take a large thickness for the heat-shielding air layer to a maximum extent in a radial direction. Therefore, it is possible to protect the fuel oil supply pipe disposed at the center, from high temperature at the outside of the pilot nozzle.

Abstract: A fire resistant, self-adhesive rolled roofing membrane is used on low sloped roofs for insulating a surface from weather. The roofing membrane includes an asphalt-saturated fibrous material having a roofing surface area, for example, roofing granules on a portion of the top surface and a clean surface area on another portion of the top surface. The roofing membrane includes an adhesive surface area on a portion of the bottom surface opposite the roofing surface area and a parting agent covered surface area on another portion of the bottom surface generally opposite the clean surface area to prevent adhering to the clean surface area when rolled. The adhesive surface area includes a layer of self-adhesive material, such as rubberized asphalt, capable of adhering to the clean surface area when strips of the roofing membrane are overlapped. The adhesive surface area is covered with a release backing to prevent adherence to the roofing surface area. The fibrous material is saturated with an oxidized asphalt with mineral filler and the rubberized asphalt adhesive material is minimized to provide fire resistance.

Title: Method and system for transmitting a chain of messages for database
Inventor: HILL MICHAEL JOHN
IPC: G06F/
Filed: 2000-09-14
Abstract: This invention consists in a process and in a transmission system of chain of database updating messages between a managing centre and a plurality of subscriber databases geographically shared. Each message includes a chain identifier (FM) and a chain index (FI) allowing to identify the message in the chain. If a message is not received following an interference in the connection, the processing of following messages can cause the locking of databases. In order to avoid this drawback, the solution consists in adding to each message a condition block (CD) which determines if this message has to be processed without reference to elements of the chain or which are the conditions linked to the previous processing of elements of the chain.

Title: Improved restraint-type differential relay
Inventor: GUZMAN-CASILLAS ARMANDO
IPC: H02H3/08
Filed: 2000-10-11
Abstract: A differential relay for protecting a power apparatus portion of a power system, such as a bus line, includes incoming and outgoing power lines on which incoming and outgoing currents are present. The incoming and outgoing currents of each phase are applied trhough current transformers and then through filtering and normalizing circuits prior to application to the differential relay. The differential relay includes a circuit for determining the presence of an external fault, and maintains security by avoiding a tripping action of the relay for said external faults. Further, the relay includes circuits which in response to the external fault evolving to an internal fault alters the operation of a portion of the relay, by increasing the gain for the restraint current, enabling a directional element for supervision of the differential relay, and for extending the immediate post-fault value of restraint current, and adding a time delay for a selected period of time, all of which are used to identify an external fault evolving into an internal fault.

Title: Optical node unit, wavelength multiplexing optical transmission system, and wavelength separating method
Inventor: SHIBAGAKI TARO
IPC: H04B10/29
Filed: 2002-06-11
Abstract: Wavelength-multiplexed light including wavelength lights is separated at periodic intervals of wavelength by means of a periodic optical filter, thereby generating wavelength groups composed of the following wavelength lights. Then, an optical switching section selects any one of the wavelength groups and introduces the selected wavelength group into a periodic optical filter. Making the period p of the periodic optical filter different from the period q of the periodic optical filter causes the wavelength lights included in each wavelength group to be outputted at the different separation ports of the periodic optical filter. As a result, each wavelength light is separated completely from the other wavelength lights.
